Protect your drivetrain with the Banks Ram-Air differential cover (MPN: 19280). Unlike conventional flat-back aftermarket covers that can cause fluid aeration and stagnant air pockets, the patented Banks design utilizes high-velocity Ram-Air scoops to force air through specialized radiation fins. In on-road towing tests, this system cooled 5X better than high-capacity flat-back covers, significantly extending the lubrication life of your gear oil.

The internal geometry is precision-engineered to improve fluid dynamics. A dedicated ring gear raceway guides fluid directly to the ring and pinion interface and out to the axle tubes and bearings, ensuring critical components stay lubricated under heavy loads. The design retains factory ground clearance and fluid capacity while providing superior heat rejection.

• Patented Cooling: Forced-air scoops and FlowThru Fins® overcome the dead air zone behind the differential.
• Fluid Management: Reduces aeration and improves lubrication flow to bearings.
• Premium Features: Includes a high-visibility sight glass, magnetic drain plug, and a 1/8-inch NPT temp sensor port.
• Rugged Construction: Durable black finish with an O-ring seal to eliminate the need for messy RTV.
• Safety Engineered: Ram-Air scoops are designed to break away if they strike an obstacle, preventing housing damage.
